The state of PyPy
summary
PyPy claims it runs pure-Python(2) code about 7.6× faster than CPython 2.7 by combining a tracing JIT and a moving garbage collector, and the latest PyPy 5.4.1 release ships improvements like a cpyext overhaul to emulate the CPython C-API and make existing C extensions (numpy, pillow) more usable. Python 3 support reached a 3.3 release and now has Mozilla-funded Python 3.5 work underway; use cffi for native libraries, mind GC vs refcount semantics, and try the portable PyPy build and resource-tracking option.
